Solving a Puzzling Physics Problem: ##15 \pm 3\sqrt{15}##
MatinSAR has given the simplest way to solve this. Taking initial velocity of the second car to be -30 m/s is wrong. That value is 0.- physicalbug

Solving a Puzzling Physics Problem: ##15 \pm 3\sqrt{15}##
"I cannot figure out what I am doing wrong" "I know v_2(6)=0, so 0=v_0+5(6) v_0=−30 ". Here you are assuming (1) acceleration to be 5 during the first 6 sec. During the first 6 sec acceleration actually is 0. (2) You are assuming the initial velocity of second car to be unknown but that is...- physicalbug
